Fungusmen spores (sunken forest) do not apply their debuff.  They don't do anything at all currently, actually.

As of now, I am uncertain if this applies to the ones from the labyrinth too.

I've noticed them acting strange in particular when the fungus that spawned them dies. Sometimes they stop working, sometimes enemies begin being able to trigger the spores too.
